The forward’s goal could not rescue his Bundesliga side from going down to the Regionalliga West team
Pierre-Emerick Aubameyang was on target in Borussia Dortmund’s 3-2 defeat to RW Essen in Tuesday’s friendly encounter.
When the breakthrough arrived, it fell Essen’s way as Benjamin Baier long range strike beat goalkeeper Roman Burki.
Aubameyang levelled proceedings in the 30th minute with a simple tap-in after connecting with Omar Toprak header off Andre Schurle’s corner kick.
The Gabonese star threw away a golden opportunity seven minutes later when he failed to put the ball into an open net from Schurle’s corner.
Five minute before halftime, Baier completed his brace after profiting from a moment of carelessness from Peter Bosz’ defenders to send a missile past Burki.
Essen got the third through Marcel Platzek in the 61st minute, with Ousmane Dembele’s goal two minutes later unable to prevent his side from losing.
